The safe use of patient lifts requires proper placement of the patient in the lifting device. For stability, the location of the patient’s center of mass, shown by the plumb bob, must always be within the sling material.

An engineering analysis can be used to determine if the ride was designed with a sufficient margin of safety.

Greg Wright documents the mechanical action of a hydraulic coupler for further analysis to determine if the coupler’s design and movements led to the failure.

Machine and Product Analysis

When examining a product case, it is imperative to determine whether the injury or loss was caused by a failure of one or more components, or if other factors were responsible.
